A.D.E Member Join Date: Jul 2011 Posts: 42 Rep Power: 14	Hi, I am currently having difficulties obtaining a reasonable agreement for Cd between experimental and numerical results (Re approximately 1 million). The numerical analysis is 2d and in the experimental procedure end-plates are used to achieve similar effect. The results are corrected for interference blockade etc!!! Does anyone know any reasons for the big difference obtained in Cd (more than 40%)? Is there anything in the published literature describing similar disagreement?? The values of Cl agree within 5%. I would be grateful for any comments. Sincerely, A.D.E
